Summary: [Tracker] Data integrity issues
Product: D
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Keywords: accepts-invalid, wrong-code
Severity: normal
Priority: P2
Component: DMD

This is a tracker for issues in the compiler and/or the D specification that
compromise the integrity of data in some way. These can include:
- holes in the D2 const/invariant system
- cases in which a variable fails to be initialised
- places where protection attributes are not honoured, making it possible to
mess with a module's internal workings
- wrong-code bugs that corrupt data
- places where measures to check data integrity at runtime cannot be relied
upon
This tracker doesn't cover ways in which the programmer can deliberately bypass
D's features that are meant to protect against data corruption. Rather, the
point is to show how we have a D that isn't as robust against data corruption
as it's cracked up to be.

It isn't supposed to help get them fixed. It's supposed to see how we're doing
towards having a D language/compiler that's robust against data corruption.
There was a discussion back then about having trackers here, and there was no
objection. If some authority has banned them since, please point me to the
statement.

I agree with Brad. Umbrella bugs seem like a great idea, until you use them.

And this one isn't even an umbrella bug, it's a personal gripe list.

Where is the keyword for data integrity issues?

When there's no open bugs in that category, there's no bugs with
the keyword. Unlike umbrella bugs which would end up being closed
and reopened as bugs are found. There's no clear 'done' with
umbrella bugs. See 1001, the stack trace bug, for a classic case of

That's true, and in principle keywords could mostly replace tracker issues. In
practice, they need to be created by someone who has the necessary access to do
so. It might be easier to get a keyword created on a small Bugzilla like this
one compared to a big one like bugzilla.mozilla.org, but still....

I agree with Brad. Umbrella bugs seem like a great idea, until you
use them.

Still, it's only the opinion of a few people. OK, so there are probably more
whom we don't know about. But clearly many people find them useful for various
reasons. The commonness of them on b.m.o is evidence of this.

There isn't, it covers too many disparate things to be a helpful category. It
has a very large overlap with wrong-code.

Nobody fixing D bugs has found them useful AFAIK. BTW this is the almost the
only remaining umbrella bug in the D bugzilla.

And this one isn't even an umbrella bug, it's a personal gripe list.

How does a collection of data integrity bugs constitute a "personal gripe
list"???

To quote the bug description:
"the point is to show how we have a D that isn't as robust against data
corruption as it's cracked up to be."
Very similar to your old "pending peeves" list. That's fine for a wiki, but
doesn't belong in Bugzilla. It doesn't contribute to getting anything fixed.

In your opinion.

It has a very large overlap with wrong-code.

How do you work that out?

What has usefulness to a specific minority of users to do with anything? The
fact remains that some people find trackers useful.

You haven't answered the question at all. How does "a D that isn't as robust
against data corruption as it's cracked up to be" equate to "a D that isn't to
some random individual's liking"?
In any case, the fact remains that we need more people's opinions before
deciding what to do with this issue. I'll start a discussion on the newsgroup
about it when I've a bit more time (hopefully this evening).
